Second Hand Car How To Return Car Deposit Refund?

Car deposit refund? - second hand car how to return

We have a deposit (€ 300) by credit card in a used car from a dealer, they said they do not have the logbook, and it takes two weeks to another is received from the DVLA so 3 weeks and still no trace of him. (He had sold the car to a man who could not afford the Finanace and had to return the car - not back, the record book)

I mean bail, there is nothing in the deposit receipt for the money is not repaid?
